Installation ease with impeccable results makes our DMC 450SL roof system a standout choice. The 1-1/2″ Snap Lock profile and DMC 450SL Clip create a continuous interlocking system that installs quickly, reducing labor costs. The concealed fastener and clip application also allow thermal expansion and contraction movement to help keep the beautiful finish straight and true.
